Multi-layer plastic container for non-oily contents

Abstract

[Problem] To provide a polyethylene container which enables a non-oily viscous content such as ketchup or the like to favorably run down when the container is inverted. [Means for Solution] A polyethylene container having at least a polyethylene resin layer on the inner surface thereof, wherein the polyethylene resin layer on the inner surface of the container contains an aliphatic amide in an amount of not less than 500 ppm but less than 4000 ppm.

1 . A multi-layer plastic container for a non-oily content having at least a polyolefin resin layer on an inner surface thereof and for being filled with the non-oily content, wherein the polyolefin resin layer on the inner surface of the container contains an aliphatic amide in an amount of not less than 500 ppm but less than 4000 ppm. 
     
     
         2 . The multi-layer plastic container according to  claim 1 , wherein at least part of said aliphatic amide is an unsaturated aliphatic amide. 
     
     
         3 . The multi-layer plastic container according to  claim 2 , wherein said unsaturated aliphatic amide has carbons in a number in a range of 14 to 24. 
     
     
         4 . The multi-layer plastic container according to  claim 3 , wherein said unsaturated aliphatic amide is an oleic amide. 
     
     
         5 . The multi-layer plastic container according to  claim 1 , wherein said polyolefin resin layer is, further, blended with an organic peroxide. 
     
     
         6 . The multi-layer plastic container according to  claim 2 , wherein said polyolefin resin layer is blended with an unsaturated aliphatic amide and a saturated aliphatic amide as said aliphatic amide. 
     
     
         7 . The multi-layer plastic container according to  claim 6 , wherein said unsaturated aliphatic amide and the saturated aliphatic amide are blended at a weight ratio of 1:0.1 to 1:4. 
     
     
         8 . The multi-layer plastic container according to  claim 6 , wherein at least two kinds of amides of oleic amide and erucic amide are contained as the unsaturated aliphatic amide. 
     
     
         9 . The multi-layer plastic container according to  claim 6 , wherein said saturated aliphatic amide is a stearic acid amide. 
     
     
         10 . The multi-layer plastic container according to  claim 1 , wherein the polyolefin resin layer on the inner surface of the container is a polyethylene resin layer. 
     
     
         11 . A packing body wherein the multi-layer plastic container of  claim 1  is hot-filled with a non-oily content. 
     
     
         12 . The packing body according to  claim 11 , wherein said non-oily content is a viscous food. 
     
     
         13 . The packing body according to  claim 12 , wherein said viscous food is ketchup.
